We’ve done a lot of work to make your compiles run as quickly as possible on our server, but we still have to transfer the PDF to your browser to display it. For large files, like a thesis with lots of images, this can take quite a while. That’s why we’ve completely rewritten our PDF viewer to only download the individual pages that you need. The round-trip time from pressing compile to seeing the updated document should now be a lot quicker for large files!

Everyone now using the in built pdf viewer will be using the new faster viewer.
